Latency before first Characteristic ValueChanged Event #32

We are developing a BLE notepad, https://www.xp-pen.com/product/516.html

SDK available: https://github.com/woodemi/notepad-sdk-uwp

The notepad collects 200 NotePenPointer per seconds and transfers the data though BLE.
But there seem to be a latency before the GattCharacteristic.ValueChanged triggered

I've tried the BluetoothLEExplorer, same issure. Is there any work around?

When developing on Android, we use BluetoothGatt#requestConnectionPriority to solve a similiar problem.
